The functional principle of worm gear sets has been unchanged for over 100 years: A spiral-shaped worm engages into a gear, forming what is called a worm gear. The axles here are shifted by 90°. Worm gears are generally used where high gear ratios (up to 150:1) have to be achieved in one step. In doing so, the high speed of an electric motor can be converted into a high torque at a slow speed.
For manufacturers of transmissions, motors and drives, Framo Morat worm gear sets are the embodiment of maximum precision and reliable, durable function. Whether in drives of automatic doors and gates, in actuators for aligning dish antennas, in linear drives of handling systems, in dosing pumps for the chemical industry or in motorized gardening tools – our worm gear sets are used successfully in numerous applications and industries.
The traditional application for our standard worm gear sets is in gear motors. A number of renowned manufacturers that serve various markets worldwide use our worm gear sets.
Medical applications pose the very highest of demands regarding precision, quiet running and long service life. This is also the case for the worm gear sets made of stainless steel, with which all moving parts of an operating table can be adjusted. 
A main use of our worm gear sets is as pump systems for purifying drinking water and waste water treatment. The use of high-quality materials ensures reliability and a long service life for our gear sets under uniform loads in continuous operation.
With decades of expertise, Framo Morat produces high-precision, low-backlash, and weight-optimized duplex worm gear sets for innovative gimbal technology in satellite antennas within the Transport Layer. These drive solutions benefit from an energy-efficient, compact design and minimal mechanical stress, ensuring precise alignment and stable signal transmission – perfectly tailored to meet the demanding requirements of modern satellite communications.
In rotary and swivel tables that position components for processing or for automated assembly, worm gear sets in duplex gear design with adjustable gearing backlash are used. Because the gearing is adjustable, instruments and components to be measured can be precisely positioned throughout their entire service life. The duplex worm gear set is especially suited for drives that require positioning at precise angles with high gear ratios.
This satellite system is the optimum solution for those who travel to the remotest corners and attach the greatest value to maximum convenience for satellite reception. Just push a button and the satellite antenna starts its fully automatic scan, identifies the satellite after a few seconds and transmits the desired broadcast.
Worm gear sets used as an azimuth slewing drive for transmitting up to 9,000 Nm of dynamic and 20,000 Nm of static loads to tracking systems with a panel as large as 60m2.
